How To Find The Cube Root of a Large Number

Lmao istg

Viryl Lucas StudyPug is pure trash, they think math has changed a lot between 2006 and 2020.

Math pug: recomeded. My mind: recommended to f*** the executive ofices.

What! You’re still getting ads about looking for Math Problems that are from 2010? Is that ad really helping?

So… 46656’s cube root is: First is we focus the last dight - it’s 6. So then 46 is between 2 and 4. So it’s 36!? I gonna tried it! 🥳

I will make a video showing how to do this.

You would express it as a cube root

64536 isnt a perfect cube tho, of course you cant solve it this way.

what is cube root of 2?

Learning 1 to 15 cubes is not enough for this type of cuberoots

Okay but..find Cuberoot of 7762392. Is it ok to remember or find the first 4 digits of 7 digit number cuberoot. But in my example that is given above first 4 digits are 7762.it is difficult to find exactly which is in between 2 perfect cubes. In this case how to we solve..?

Most numbers don't have integer square roots and can be expressed in relation to the span of two prefect squares they're between, same with cubes. 23 has no roots, being prime, however it is 2 less than 5^2 which is a linear relationship to the next largest square, and 2^2 less than 3^3 which is a square relationship with the next largest cube.

True, there can be some such cases. Finding HCF of the number and knowing divisibly works. I think cross checking is the way to go. But this method is dope too for solving exam questions where it can be solved.

How accurate do you want your answer to be? I can give your answer to 10 digit accuracy , pen/paper only, in less than 20 minutes, on about 2/3rds of a sheet of paper. So what is your 4000 digit number?

@@deidara_8598 Sorry, i am not interested in finding the cube root of perfect cubes because the talent is perfectly useless in the real world! There is not one useful thing you could ever do with such a talent. Maths is a tool with which we accomplish USEFUL THINGS As i stated, i can find the answer to your problem to 10 digit accuracy in less than 20minutes, pen paper only. About 2/3rds of a sheet. Regardless of whether it is a perfect cube To start, assuming your number is actually 4000 digits we can begin by sayingthe answer is obviously the cube root of 3.8003194117 x 10^1333. So we need to find the cube root of 3.8003194117, and we have accomplished our task. To learn to do that it wont help at all for you to be watching these goofy videos about how to find cube roots of perfect cubes. So the real question is one of whether or not your question was even serious.

@@deidara_8598 Thats the point, it is just as easy if it IS NOT a perfect cube. There is no utility in being able to find the sqrt or cube rt of perfect squares and cubes Square rt is quite simple, cube roots is more involved. No one teaches a practical long division method to find cuberoots on utube. A few begin, but they always decide it is to cumbersome to be practical. It is not, you just need to think outside the box a bit, and figure it out. Here is a long division method to find CRs, but he doesnt figure out how to make it practical. Can you? ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-y0qWHMmCY4E.html As for your question, I assume you want an answer to 1333 digits of accuracy. That is do able but it would take many thousands of hours, and many thousands of pages of arithmetic. There is no reason to want to do that anyway. No one needs that kind of accuracy.

Yes, you stumbled onto the biggest flaw of all these videos: these are perfect cubes. If you watch his similar videos on square roots, people are complaining about the same thing. The examples over there are perfect squares. So this method is actually completely useless lol. His videos are still great. But this stuff is pointless to learn.

You are finding that these tricks are useless. If you want to you can learn to find square roots and cube roots of any number with pencil and paper only

It only works on perfect cube unfortunately

Make the cube root of 250 into cube root of 50 times cube root of 5. Next turn the cube root of 50 in three parts, cube root of 5, cube of 5, cube root of two. Together you should have cube root of 5 times, cube of 5 times cube root of 5, and times the cube root of 2. You will then find the three cube roots of 5 would equal 5 and you will also be left with cube root of 2. So your answer will be 5 times cube root of 2.

@@themooanator8701 Lol. Hey genius. All that youdid there is teach him to factor 250. That does not help to find the CR of 250. Because it is no easier to find the CR of 2 and multiply the answer by 5, than it is to just find the CR of 250 in the first place. Which you can teach yourself to do with pen/paper, to very high accuracy, in a few minutes, using very little paper space

@@ronalddump4061 I was trying to show him the exact answer in terms of factoring because he didn't want the decimal form and didn't know how to express it without being an exact number.

@@themooanator8701 Bu,bu, but, but the most concise way to express the cube root of 250, "w/o expressing it in decimal form" Is, to simply say "the cube root of 250". Btw, do you even know how to calc the answer in decimal form, with pen and paper only, , out to say 7 places? In a practical amount of time and space, that is? I can assure you a frantic search of utube wont help, there is not even one vid on the subject, among the thousand vids pretending to be on the subject. Apparently i am the only person on earth who can do it. (-;

@@ronalddump4061 Not hard my guy. And no. The best way to express the cubed root of 250 would be five times the cube root of 2. No point in knowing how to write the exact answer 7 places when no one would want it rounded seven places. I also doubt you can do it in a reasonable amount of time.

It is not a perfect cube

This method is to take out the cube root of perfect cubes 12996 is not a perfect cube

It's not possible to find the cube root of any number, as it would just result in a decimal that could be irrational. Don't label his method as dishonest, because there are many uses for if it's a perfect cube. Besides, you don't need a method to find the cube root of any number because you can use his method and round up and down as needed. In addition, of course the numbers aren't random. He's selected them before so the video is quick and efficient, otherwise he'd spend unnecessary time thinking of numbers in the video.

@@atharvahalapeti9775 Stupid comment What is the cube root of 2003469876 accurate to 7 digits. Or 5 digits. Or 10. Lol, what is"impossible" about that? There is nothing challenging or useful about being able to find the cube root of a two digit number cubed. There IS something useful and challenging about being able to find the cube root of just any number you might need to find the cube root of What's this about "irrational" numbers?
